Pupa. — Length 2.6 to 3 mm. Color light yellowish white. Shape 

 broadly elliptical, tapering to oval end which is obtusely pointed and 

 which bears a pair of spines each terminated by a pair of minute, 

 recurved hooks. Head reflexed, snout extending to middle portion 

 of body and bearing at middle a pair of minute hairs (one on either 

 side). On front margin of prothorax are a pair of minute tubercu- 

 late spines, on either side of the middle of the pronotum, a tuberculate 

 spine posterior to each of the above pairs and a pair of minute tuber- 

 culate spines on either side of the middle along the posterior margin. 

 A single, dorsal, tuberculate spine on mesonotum. Dorsal abdominal 

 surface more or less tuberculate, bearing minute short spines. A 

 single, tuberculate spine occurs near distal end of femur of middle 

 and hind leg. 



Adult. — Apion hibisci. The description by Fall appeared in a re- 

 cent number of this Journal (Vol. XXVI, p. 219) in his paper 

 on "' New North American Species of Apion," and need not be re- 

 peated here. According to Prof. Fall, hibisci belongs to Section IV 

 of his Synopsis (Trans. Am. Ent. Soc, 1898), and would by the table 

 fall near attcnuatum, after which it may best be placed; differing by 

 its stouter form, broader thorax, more parallel elytra, more basally 

 inserted antennae, and paler tibise and tarsi. The sexual differences 

 are very feeble, consisting only in the slightly longer beak in the 

 female. 



The presence of numerous galls on a plant resulting in the petioles 

 being swollen and the stem deformed and misshapen disfigures it 

 greatly and interferes with a normal growth although no dead plants 

 were observed as a result of such infestation. Infested plants had 

 normal foliage and appeared to flower as well as those which were 

 not infested. Should this insect prove injurious in a nursery or 

 garden, cutting and burning infested stems before the beetles emerge 

 is suggested as a method of control. 



Bruchus hibisci Oliv. 



This species was described by Olivier in 1795 (Ent., IV). Ac- 

 cording to Blatchley (Coleoptera of Indiana) it is common in the 

 southern two thirds of Indiana occurring from April 13 to Novem- 

 ber 1, breeding in the seeds of rose-mallow and during the spring and 

 summer frequenting the flowers of red-bud. dogwood, red haw, etc.
